### OCR Widget

PC-DMIS uses this widget to import GD&T tolerances from a drawing with Optical Character Recognition (OCR). The widget appears if you select either GD&T Selection Mode (from Capture) () or GD&T Selection Mode (from File) () from the Graphic Modes toolbar. For information on the Graphic Modes toolbar, see "Graphic Modes Toolbar" in the "Using Toolbars" chapter.

There are often multiple steps with instructions on the OCR widget for a given GD&T tolerance definition. For example, you often need to first select a datum feature (or features) from the CAD model and later select the considered feature (or features). These instructions and your selections occur across multiple steps.

OCR Widget for the highlighted GD&T tolerance

1. This handle lets you drag and reposition the widget.

2. Feature - This box defines the name of the GD&T tolerance.

3. Back - This button only appears if there are multiple GD&T tolerances on a .pdf page, and you have skipped one or more of them with the Skip button. If you then click Back, the software returns to the skipped tolerance and highlights it in the Selection Preview window.

4. Skip - This skips the current GD&T tolerance in the Selection Preview window and highlights the next available GD&T tolerance on the page. If there's only one GD&T tolerance, the software asks if you want to proceed to the next page. If there are no more .pdf pages with GD&T tolerances, the software asks if you want to exit the GD&T import process. This button only functions on GD&T tolerances that are imported through a file. If you need to go back to a skipped item on a previous page, you must start the file import again.

5. Cancel - This cancels the OCR process and closes the OCR widget and the Selection Preview window.

6. Accept - This accepts the selected features for the GD&T tolerance and moves onto the next tolerance.

7. This field shows the instructions for the current step. You need to use QuickFeatures to select the indicated feature in the Graphic Display window

8. Previous - This goes back one step.

9. Remove - This removes the selected feature from the current step.

10. Next - This accepts the selection for the step and goes to the next step in the definition. This button becomes enabled once you've defined the minimum number of features. The temporary callout in the Graphic Display window updates as you progress through the definition:
